Before emailing H and K last night I had already attempted assigning a static IP within the router to the WMI device. I tried it two ways. First I assigned it a static IP using the last number within the range of my DHCP. Got nothing. Then I assigned it a static IP within the range of my router, but outside of the DHCP range. Still nothing. Both of these were attempted with and without a gateway being assigned. With each change I would check the lease list to see if the WMI would show up. Nothing there. And of course I could not Ping the device after each change.

That was when I made the decision to email H and K. I thought one of the above attempts would have worked. If I'm honest, the thing works fine in AP mode, but it would just be nice to keep my iPad connected to the internet while also controlling the amp. It is after all designed to do just this. (Clearly a first world country problem... lol That's why I refuse to let it frustrate me)

On the upside I got a great workout since the device is upstairs and I had to keep coming downstairs to the PC/router tether!

Advice elsewhere, (can't claim it as original thought), is that it is perfectly feasible to set your WMI up with an address outside of the DHCP range as long as it is on the same subnet. In fact some people say it is preferable. You seem to be pretty tech savvy so apologies if this is a tad insulting but just in case, if your DHCP uses say 128.112.16.0 - 128.112.16.64 then you must use 128.112.16.X for your static address (with X > 64 of course). Keep the first 3 figures of the address the same to stay on the same subnet. If you don't you are effectively defining a second independent network which brings in the idea of Virtual Networks and your router will have to support that concept and be set up correctly to apply it. Otherwise you may need to run twin network adapters, and tablets don't do that as far as I know.

Try setting it up with a correct valid IP based on the above, and with full supporting info, like the Gateway IP, then if it works start removing one bit at a time until you slim it down to only what you want. You could also make sure that any firewall software is told about the range of IP addresses you will need. That may be set up to allow comms between only a restricted IP range and to deny all other IP addresses and a new rule may need to be added for your static address or the existing one may need to be expanded. Sometimes this range may even somehow be less than the full DHCP range and you won't know until DHCP tries to allocate one high up its range, not necessarily a common occurrence.

It's frustrating I know but you may have to prepare yourself to accept that you just may not be able to do this. If that's the case then I reckon it's daft on H&Ks part to set things up this way. When I started out playing with the app I stuck to cabled and made sure to buy a cheap laptop (Chimp brand!) to dedicate to the job. Then I ran into problems with my cheap Chinese MIDI adapter. Then the idea of On The Go cables. You won't have that problem at least. You'll get this up and running soon. I know from long experience, network problems like this are a pain until you get it right, sometimes without even knowing why, and then they just evaporate and it works.

I really appreciate the encouragement, Bordon. Your detailed explanations never fall short and I always seem to learn something from your posts. I didn't explain it well earlier, but I actually did try the subnet approach. Sadly the term subnet was escaping me at the time.

I have pretty much accepted that it may not work, but I enjoy a good puzzle. Truth be told it was getting late last night when I attempted the subnet approach so I'll revisit that approach while I'm thinking more clearly.

My router currently has quite a bit going on. I have another router I may use as a test bed. It would simplify things as I could have everything accessible in a small work space. Of course I could also bring the amp downstairs. Not sure why I didn't think of that last night. By using another router which has a very basic setup and WPS capability I can use WMI simple setup via WPS. After doing so I hope to able to see what the WMI needs with respect to configuration and then apply that to the router I'm want to use.

Your firewall comments are spot on as I didn't consider to evaluate those settings. I'll have to look into that.

I'm optimistic H and K will reply to my email, but from what others have posted I wonder if perhaps a Facebook post would be more efficient. Personally I eschew Facebook so I'll wait a bit before going that route.

My router is fully up to date (apple time capsule), but think this recommendation on the wmi-1 wifi ssid is to do with the protocol with which the wmi-1 network is generating to allow the app to connect.Anyone else get this? Not sure if this explains my intermittent drop outs where the iPad loses connectivity with the amp.
